Bearing - NU 4908 DKF
Product detailed description
Bearing - NU 4908 DKF
NU 4908 DKF is a single-row cylindrical roller bearing with dimensions 40 × 62 × 22 mm (d×D×B). In the NU design, the rollers are guided by two flanges on the outer ring, while the inner ring has no flanges. The bearing therefore supports high radial loads and allows axial displacement between the shaft and housing in both directions.
Key features
- Designation: NU 4908 DKF
- Type: single-row cylindrical roller bearing, NU design
- Dimensions d×D×B: 40 × 62 × 22 mm
- Manufacturer: DKF
- Load: high radial loads; the NU design is not intended to carry axial load
- Axial displacement: in both directions within the bearing
- Mounting: separable inner ring simplifies mounting and removal
Applications
The bearing is typically used as a non-locating bearing in gearboxes, electric motors, pumps and industrial machinery where radial forces must be supported while shaft length changes, for example from thermal expansion, need to be accommodated.
Selection and mounting
Before ordering, compare the complete designation, dimensions and required internal clearance with the equipment documentation. Axial forces must be carried by another bearing or structural element. Do not mix rings from different bearings; keep all parts clean, use the specified fits and ensure correct lubrication.
